That is to say, metals "capable of being easily fused, i.e. easily meltable, at relatively low temperatures."

That article lists several known alloys, most of them with melting points less than 100 C.

By the way, for some of these recipes, especially those containing alkaki, or alkalai earth metals (groups 1 and 2 on the periodic table), it is important to check, look up, reactivity data, because some of those alloys react spontaneously with room temperature air.

As an example, NaK, alloys of sodium and potassium, have room temperature melting points, but they also react, burn, into caustic white dust, spontaneously on contact with air.
